Modern thin-and-light laptops ship with one or two USB-C ports and nothing else. A USB hub expands that into HDMI output, USB-A ports for legacy peripherals, card readers, and power pass-through — all from a device small enough to fit in a pocket. The challenge is that hub quality varies enormously, and the cheap plastic ones cause real problems: bandwidth throttling that slows your external drive, overheating that kills the hub in months, or HDMI that caps at 4K/30Hz when you need 60Hz.
This guide explains what the specs actually mean, how to match a hub to your specific laptop and use case, and which models are worth buying.
Hub vs. docking station — which do you need?
These terms get used interchangeably but describe different products.
A USB hub (this guide) is bus-powered — it draws all its power from your laptop's USB-C port. No external power brick, fully portable, fits in a bag. Maximum power delivery is around 85–100W PD (limited by what the hub can pass through from a wall charger). Supports one external display on most designs. Port count: 4–9 typically.
A docking station has its own power adapter, supports multiple external displays simultaneously, handles higher power delivery (up to 140W+), and stays on your desk permanently. For home offices with fixed setups, a dock is better. See our guides on MacBook docking stations and USB-C docking stations.
Use a hub if: you travel regularly, you need a single external display, or you want to avoid a power brick on your desk. Use a dock if: you need dual displays, 96W+ laptop charging, or more than 8 ports simultaneously.
USB standards decoded
The USB naming conventions are a mess. Here's what the specs mean practically:
USB 3.0 / USB 3.2 Gen 1: 5 Gbps. Fast enough for SSDs (up to ~400 MB/s real-world), more than sufficient for mice, keyboards, and webcams.
USB 3.2 Gen 2: 10 Gbps. For fast NVMe enclosures and high-bandwidth devices. Most hubs in this price range top out at Gen 1 (5Gbps).
USB 2.0: 480 Mbps. Adequate for mice, keyboards, USB audio, card readers. Not adequate for external drives.
HDMI 1.4: 4K at 30Hz. Fine for a secondary productivity monitor displaying static content, noticeably choppy for video playback or fast scrolling.
HDMI 2.0: 4K at 60Hz. The minimum for a comfortable primary display. 1080p at 144Hz also supported. This is what to look for.
Thunderbolt 3/4: 40 Gbps. A superset of USB-C that supports dual displays, higher bandwidth, and daisy-chaining. Most hubs use USB 3.x, not Thunderbolt — if you need Thunderbolt capabilities, look for hubs explicitly marketed as TB3/TB4 compatible.
Power delivery considerations
If you want to charge your laptop through the hub, the hub must support Power Delivery (PD) passthrough. Key numbers:
- MacBook Air M2/M3 (13"): Charges at 30W minimum, 67W for fast charge. An 85W PD hub covers this comfortably.
- MacBook Pro 14": Needs 67W for normal operation, 96W for full-speed fast charge. 85W PD is sufficient for normal use; get 100W PD if you want fast charge.
- MacBook Pro 16": Requires 96W+ to maintain charge under load. Most hubs top out at 85W — they'll keep the battery from draining but won't charge under heavy CPU load. A docking station is better for this laptop.
- Windows ultrabooks (Dell XPS 13, Lenovo ThinkPad X1): Most charge at 45–65W. An 85W PD hub is sufficient.
The hub's PD rating is the maximum it can pass through. Some of that power gets used by the hub itself (3–5W), so a "100W PD" hub delivers roughly 95W to the laptop.
Our top picks
1. Anker 332 USB-C Hub (5-in-1) — Best compact option
The Anker 332 is the portable hub for users who want the minimum viable port set with no excess. It provides: 4K/60Hz HDMI (HDMI 2.0), one USB-C 5Gbps data port, and two USB-A 3.0 ports. No card reader, no PD charging — just display output and peripheral ports.
The no-charging design isn't a compromise if you have a spare USB-C port for your charger. What you gain is simplicity — no thermal management of a PD passthrough circuit, which means the hub runs cooler and doesn't throttle. The aluminum housing dissipates the modest heat from a non-charging hub effectively.
At roughly the size of a flash drive attached to a short cable, it disappears in a laptop bag. Anker's build quality is consistently better than generic alternatives at this size — the housing doesn't flex, the cable connector is reinforced, and the HDMI output actually delivers 4K/60Hz instead of silently defaulting to 30Hz.
Best for: Travel, minimalist setups, users with a dedicated laptop charger who just need display output and peripheral ports
2. Anker 543 USB-C Hub (7-in-1) — Best with power delivery
The 543 adds SD and microSD card readers and 85W PD passthrough to the compact form factor, making it the daily driver for MacBook Air users who want one device for everything. Port count: 4K/60Hz HDMI, 85W USB-C PD, one USB-C 5Gbps data, two USB-A 3.0 (one USB-A 2.0), SD card reader, microSD reader.
The 85W PD covers MacBook Air M2/M3 (13" and 15") and most Windows ultrabooks at full-speed charging. For MacBook Pro 14" under heavy load, the 85W approaches the limit — adequate for most usage, not full-speed charging during sustained CPU-intensive work.
The card reader is a genuine addition for photographers and videographers. A separate USB-A card reader is an extra device to carry; having it built in and running USB 3.0 speeds means faster imports directly from a camera card. The hub uses an aluminum exterior for heat dissipation, and the PD circuit doesn't cause throttling during normal use.
Weight is roughly 90g — heavier than a minimal 5-in-1 but still bag-portable.
Best for: MacBook Air users who need laptop charging + display + card reading from one portable device
3. Hiearcool USB C Hub (7-in-1) — Best value build
The Hiearcool 7-in-1 provides a similar port set to the Anker 543 at a lower price point: 4K HDMI, 100W PD passthrough, USB-C 3.0, two USB-A 3.0 ports, SD card reader, and microSD reader. The 100W PD rating edges out the Anker on paper — useful for MacBook Pro 14" users who want headroom.
The aluminum housing feels solid and runs warm but not hot under sustained use. The HDMI output supports 4K/30Hz or 1080p/60Hz — note the 30Hz cap at 4K, which means this hub is better suited to a secondary monitor than a primary display for fast-moving content. The Anker 332 and 543 both offer 4K/60Hz; the Hiearcool's HDMI is its relative weak point.
Where the Hiearcool wins is value: it's consistently priced below the equivalent Anker options while offering comparable build quality. For users who need PD passthrough and a card reader but don't need 4K/60Hz HDMI, it's an excellent choice.
Best for: Budget-conscious buyers who need PD passthrough and don't require 4K/60Hz on the external display

Setup and compatibility notes
MacBook port selection: On MacBooks with multiple USB-C/Thunderbolt ports, the left-side ports have higher bandwidth priority. Use the hub on the left side for best HDMI and storage performance.
M1/M2/M3 Mac external display limits: Base-chip Macs (MacBook Air M1/M2/M3, MacBook Pro M2/M3 base) support only one external display natively. A second external display requires DisplayLink technology — a powered dock with DisplayLink chip, not a passive hub. No hub in this guide supports dual displays on base-chip Macs.
Don't daisy-chain hubs: Plugging one USB hub into another splits the bandwidth both hubs share. If you need more ports, get a hub with more ports, or upgrade to a docking station.
Thunderbolt ports and non-Thunderbolt hubs: A USB-C hub plugged into a Thunderbolt port works fine — it uses USB 3.x bandwidth only, leaving Thunderbolt capabilities idle. This is not a problem; the hub functions normally. You just won't access the higher Thunderbolt bandwidth unless you use a Thunderbolt-specific hub or dock.
When to upgrade from a hub to a dock
A hub stops being the right tool when:
- You need two or more external displays simultaneously
- You're running a 16" MacBook Pro and need 96W+ charging under load
- You want more than 8 ports without daisy-chaining
- You need Thunderbolt-bandwidth storage (40Gbps for fast NVMe enclosures)
At that point, our guides on MacBook docking stations and USB-C docking stations cover the dedicated desk hardware.
Frequently asked questions
Will any USB-C hub work with my MacBook Air M2? Yes — USB-C hubs are compatible with any USB-C port regardless of chip generation. The constraint is external display count: base-chip MacBook Air M2/M3 supports one external display. A second display requires a DisplayLink dock, not a hub.
Can I charge my laptop through the hub? Only with hubs that include Power Delivery (PD) passthrough. The Anker 543 (85W) and Hiearcool (100W) both support this. The Anker 332 does not. Match the wattage to your laptop's charger spec.
Why does the HDMI only show 4K/30Hz instead of 60Hz? Either the hub uses HDMI 1.4 (which caps at 4K/30Hz) or the connection is bandwidth-limited due to using a USB 3.0 port rather than a Thunderbolt port. The Anker 332 and Anker 543 both use HDMI 2.0 and deliver 4K/60Hz via Thunderbolt or USB 3.2 Gen 2 ports.
Can I use a USB hub with a Chromebook? Yes — USB-C hubs are plug-and-play on ChromeOS. HDMI output, USB-A devices, and card readers all work without drivers.
Hub vs. USB-C to HDMI adapter — which is better? A dedicated adapter (USB-C to HDMI only) is more reliable for single-display use because it has less complexity and less bandwidth competition. A hub is better when you need display + peripherals + charging from one cable.
